The Joker

The Joker is a fictional super villain created by Bill Finger, Bob Kane, and Jerry Robinson who first appeared in the debut issue of the comic book Batman (April 25, 1940) published by DC Comics . Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for the Joker's design, while acknowledging Finger's writing contribution. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman. The Joker has also been included in many other platforms such as the Arkham game series, the DC animated universe, Young Justice, graphic novels, and the Nolan trilogy of batman movies . His most famous quote is "Why so serious?" and his worst deed was killing Jason Todd .
